Tutorial Setup Blynk untuk Arduino / Nodemcu ESP8266 / Wemos D1

 Tutorial Setup Blynk untuk Arduino / Nodemcu ESP8266 / Wemos D1

 

        Pada kesempatan kali ini saya akan menjelaskan mengenai step by step setup blynk agar terhubung ke arduino melalui internet. caranya sangatlah mudah yang pertama yaitu harus instal terlebih dahulu aplikasi blynknya bisa di playstore atau di Appstore. setelah instal aplikasinya teman-teman bisa ikuti cara lebih jelasnya yang ada di video dibawah ini. untuk koding contohnya bisa saya kasih lihat seperti dibawah ini.  

a. Nodemcu ESP8266 / Wemos D1

b. Contoh Program Arduino 

#include <Wire.h>

#define  BLYNK_PRINT Serial  

#include <SPI.h>

#include <ESP8266WiFi.h>

#include <BlynkSimpleEsp8266.h>

#include <SimpleTimer.h>

#include "MAX30105.h"

#include <LiquidCrystal_I2C.h>

#include "heartRate.h"

#include <Adafruit_MLX90614.h>

LiquidCrystal_I2C lcd(0x27, 16,2);

MAX30105 particleSensor;

Adafruit_MLX90614 mlx = Adafruit_MLX90614();

float TargetC;

const byte RATE_SIZE = 4; //Increase this for more averaging. 4 is good.

byte rates[RATE_SIZE]; //Array of heart rates

byte rateSpot = 0;

long lastBeat = 0; //Time at which the last beat occurred

float beatsPerMinute;

int beatAvg;

int counter;

char auth[] = "hgjhgjTJUIYRgfhjjhrerewiuoiuokjhkjgfh";

timer.setInterval(1000L, sendSensor);

}

void loop()

{

    // Initialize sensor

  if (!particleSensor.begin(Wire, I2C_SPEED_FAST)) //Use default I2C port, 400kHz speed

  {

    Serial.println("MAX30105 was not found. Please check wiring/power. ");

    while (1);

  }

  Serial.println("Place your index finger on the sensor with steady pressure.");

  particleSensor.setup(); //Configure sensor with default settings

  particleSensor.setPulseAmplitudeRed(0x0A); //Turn Red LED to low to indicate sensor is running

  particleSensor.setPulseAmplitudeGreen(0); //Turn off Green LED

  long irValue = particleSensor.getIR();

  if (checkForBeat(irValue) == true)

  {

    //We sensed a beat!

    long delta = millis() - lastBeat;

    lastBeat = millis();

    beatsPerMinute = 60 / (delta / 1000.0);

    if (beatsPerMinute < 255 && beatsPerMinute > 20)

    {

      rates[rateSpot++] = (byte)beatsPerMinute; //Store this reading in the array

      rateSpot %= RATE_SIZE; //Wrap variable

      //Take average of readings

      beatAvg = 0;

      for (byte x = 0 ; x < RATE_SIZE ; x++)

        beatAvg += rates[x];

      beatAvg /= RATE_SIZE;

    }

  }

  counter++;

if(counter > 100){

 counter = 0;

 mlx.begin();

 TargetC = mlx.readObjectTempC();

 lcd.setCursor(0,1);

 lcd.print("Temp= ");

 lcd.print(TargetC);

 lcd.println(" 'C     ");

 if (TargetC <=  37.5) {

   digitalWrite(speakerPin, LOW);  

   digitalWrite(ledmerah,LOW);  

   digitalWrite(ledhijau,HIGH);

  }

 if (TargetC > 37.5 ) {

   digitalWrite(speakerPin, HIGH);

   digitalWrite(ledmerah,HIGH);

   digitalWrite(ledhijau,LOW);

   delay (3000);

 }

      

 Blynk.run();

 timer.run();

}

  lcd.setCursor(0,0);

  lcd.print("BPM= ");

  lcd.print(beatsPerMinute);

  lcd.println("       ");

      

  Serial.print("IR=");

  Serial.print(irValue);

  Serial.print(", BPM=");

  Serial.print(beatsPerMinute);

  Serial.print(", Avg BPM=");

  Serial.print(beatAvg);

  if (irValue < 50000)

    Serial.print(" No finger?");

  Serial.println();

}
